Documentation

Install

with npm (recommended):

npm install jsoneditor

Note that to use JSONEditor in Internet Explorer 11, it is necessary to load a polyfill for

Promise
in your application.

Use

<!-- when using the mode "code", it's important to specify charset utf-8 -->
<meta charset="utf-8">

<link href="jsoneditor/dist/jsoneditor.min.css" rel="stylesheet" type="text/css">
<script src="jsoneditor/dist/jsoneditor.min.js"></script>


<div id="jsoneditor" style="width: 400px; height: 400px;"></div>

<script>
    // create the editor
    const container = document.getElementById("jsoneditor")
    const options = {}
    const editor = new JSONEditor(container, options)

    // set json
    const initialJson = {
        "Array": [1, 2, 3],
        "Boolean": true,
        "Null": null,
        "Number": 123,
        "Object": {"a": "b", "c": "d"},
        "String": "Hello World"
    }
    editor.set(initialJson)

    // get json
    const updatedJson = editor.get()
</script>

Build

The code of the JSON Editor is located in the folder

./src
. To build jsoneditor:
  • Install dependencies:
  npm install
  • Build JSON Editor:
  npm run build

This will generate the files

./jsoneditor.js
,
./jsoneditor.css
, and
minified versions in the dist of the project.
  • To automatically build when a source file has changed:
  npm start

This will update

./jsoneditor.js
and
./jsoneditor.css
in the dist folder on every change, but it will NOT update the minified versions as that's an expensive operation.

Test

Run unit tests:

npm test

Run code linting (JavaScript Standard Style):

npm run lint

Custom builds

The source code of JSONEditor consists of CommonJS modules. JSONEditor can be bundled in a customized way using a module bundler like browserify or webpack. First, install all dependencies of jsoneditor:

npm install

To create a custom bundle of the source code using browserify:

browserify ./index.js -o ./jsoneditor.custom.js -s JSONEditor

The Ace editor, used in mode

code
, accounts for about one third of the total size of the library. To exclude the Ace editor from the bundle:
browserify ./index.js -o ./jsoneditor.custom.js -s JSONEditor -x brace -x brace/mode/json -x brace/ext/searchbox

To minify the generated bundle, use uglifyjs:

uglifyjs ./jsoneditor.custom.js -o ./jsoneditor.custom.min.js -m -c
